Title: Recovering method for hydrofluoric and nitric acids
Inventor: ODA TERUMI
IPC: C01B21/46
Filed: 1978-03-20
Abstract: PURPOSE: To recover efficiently and cheaply hydrofluoric and nitric acids at high concn. with a small-sized aparatus by electrodialyzing waste hydrofluoric and nitric acids with an electrodialyzer provided with monovalent ion selecting cation and anion exchange membranes.  
     CONSTITUTION: When waste hydrofluoric and nitric acids contain many metal ions such as Fe and Ni ions, the acids are fed to an electrodialyzer and passed through line 5 for waste hydrofluoric and nitric acids through a process for adding polybasic acid such as sulfuric acid in an amt. corresponding to the amt. of the metal ions. When the acids contains many solid particles, the acids are passed through a process for removing coarse solid particles with a thickener and a process for removing fine solid particles with a centrifugal separator, super decanter, etc. prior to feeding to the dialyzer. H +  in the acids can pass through monovalent ion selecting cation exchange membranes C, yet polyvalent metal ions cannot pass. On the other hand, F -  and NO 3   -  can pass through monovalent ion selecting anion exchange membranes A, yet SO 4   2- , etc. cannot pass. Accordingly, pure hydrofluoric and nitric acids can be obtd. at the outlet side of line 6. Hydrofluoric or nitric acid is circulated as an electrolyte.
